Abstract

Background The skeleton and liver are frequently involved sites of metastasis in patients with metastatic renal cell carcinoma (RCC). Objective To analyze outcomes based on the presence of bone metastases (BMs) and/or liver metastases (LMs) in patients with RCC treated with targeted therapy. Design, setting, and participants We conducted a review from the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) of 2027 patients with metastatic RCC. Outcome measurements and statistical analysis We analyzed the impact of the site of metastasis on overall survival (OS) and time-to-treatment failure. Statistical analyses were performed using multivariable Cox regression. Results and limitations The presence of BMs was 34% overall, and when stratified by IMDC risk groups was 27%, 33%, and 43% in the favorable-, intermediate-, and poor-risk groups, respectively (p < 0.001). The presence of LMs was 19% overall and higher in the poor-risk patients (23%) compared with the favorable- or intermediate-risk groups (17%) (p = 0.003). When patients were classified into four groups based on the presence of BMs and/or LMs, the hazard ratio, adjusted for IMDC risk factors, was 1.4 (95% confidence interval [CI], 1.22-1.62) for BMs, 1.42 (95% CI, 1.17-1.73) for LMs, and 1.82 (95% CI, 1.47-2.26) for both BMs and LMs compared with other metastatic sites (p < 0.0001). The prediction model performance for OS was significantly improved when BMs and LMs were added to the IMDC prognostic model (likelihood ratio test p < 0.0001). Data in this analysis were collected retrospectively. Conclusions The presence of BMs and LMs in patients treated with targeted agents has a negative impact on survival. Patients with BMs and/or LMs may benefit from earlier inclusion on clinical trials of novel agents or combination-based therapies.
